Catalyst for preparing sorbitol and sorbitol preparation method

The invention relates to a catalyst for preparing sorbitol and a preparation method of sorbitol, the catalyst comprises a carrier and Ru and Cu loaded on the carrier, the mass percentage content of Ru in the catalyst is 3%-4%, the mass percentage content of Cu is 0.5%-1%, and the carrier is activated carbon. According to the catalyst provided by the invention, Ru and Cu are simultaneously loaded on the carbon-based carrier, so that compared with a Ru-loaded carbon-based carrier in the prior art, the conversion rate and the yield of sorbitol synthesized by glucose hydrogenation can be further improved. 本发明涉及一种制备山梨醇的催化剂以及山梨醇制备方法，所述催化剂包括载体和负载于所述载体上的Ru和Cu,所述催化剂中Ru的质量百分含量为3%-4%，所述Cu的质量百分含量为0.5%-1%，所述载体为活性炭。本发明提供的催化剂，通过在炭基载体上同时负载Ru和Cu，相较于现有技术中的Ru负载的炭基载体，能够进一步的提高葡萄糖加氢合成山梨醇的转化率和产率。
